The 2 is a purge line, meant to clear any pressure in the nozzle and wipe it off before a print. It can be edited in your Start G-code on the printer settings tab > custom g-code on prusaslicer.
The 1 is a skirt, meant to get rid of any last few hanging bits of filament and start a clean print (sometimes the purge line doesn’t get everything off the nozzle). It can also be used to gauge any last minute adjustments to your z offset. If the nozzle is too close or too far, you’ll know before the print actually starts. I find that the skirt can be disabled if you’re using a brim, since it’s redundant at that point. Some who have fine tuned printers may opt not to use one at all without much issue. It isn’t meant as any kind of draft shield as another person said - that’s a separate setting. It’s just a failsafe for the cleanest prints possible, avoiding hanging bits of filament, blobs from built up pressure, and incorrect z height. The first layer is the most important so everything that helps the first layer helps the rest.
Doubtful. The main reason I could see a 3D printer starting a fire is either thermal runaway, often caused by bad software (on cheap printers) or electrical issues. You can check your wiring and make sure that nothing looks loose and all of your cables are in good condition. You can also make sure that your printer firmware is up to date. It’s a Prusa right? I think you should be safe from software failure in that case, as they’re quality.
If you’re really concerned about it, you can also move your power supply, and even your mainboard, outside of the enclosure by using longer cables. This would keep the majority of the electrical components away from the foam and heated box. From my position I don’t see an issue, but that’s my personal opinion – not legally accountable information. I will say that Stefan on CNC Kitchen uses foam as well, to get rid of ringing in prints. If you decide to go through with it, just use common sense and check to see if anything is hot. You might also get some benefit out of looking into silent stepper motors/drivers and trying to make the printer itself quieter.
I was in my early 20s when I started. Wanted the calming effects of nicotine, was into other similar interests, and was dating someone who also got into it. He was actually the second vaper I’d dated, so you could say it took me a while to be interested.
I’d had a couple cigs before but I never considered myself a smoker and didn’t take to it. Vaping became a huuuge hobby for me. Learning about different mods, building your own coils, DIY e-juice, etc. I was vaping all day, all the time, pretty much as soon as I woke up (at the lowest amount possible though). It was a nice flavor and chemical pick me up when I was on edge. Sort of like a physical distraction. I vaped for 5 or so years. The lasting effects I’ve noticed are that sometimes I miss it. That’s it. It was pretty hard to quit, mostly because I didn’t want to. I had a lot of resistance, because it became a passion for me. But nicotine regulations started to suck, and that same partner quit as well. I got really sick with a flu and didn’t vape during it. Then, I didn’t start again after I got better. I had dreams about it, and it took a bit for me to want to move on.
The thing is, though, I don’t feel any different now than when I was vaping constantly. It doesn’t improve your life that much. It’d be great if it could be an occasional thing, like alcohol or dessert is, but it’s hard to not do it all the time if you’re doing it at all. And you get to an equilibrium where it just doesn’t feel that strong. Hence the constant clouds.
The most annoying part about it is that it becomes like a security blanket. You have to take it everywhere. Forget it for work? Guess you’ll just be late today. Have to sit for a movie? Man it sucks not to vape inside. Flying for hours? What a nightmare, can’t wait to land and go outside.
It was annoying to not feel myself if I ever decided to leave my vape behind. And blowing clouds out of my car was great, but it sucked having to wipe down my car windshield all the time due to the glycerin condensation. Same with inside – no smoke on the walls, but the glycerine would hang around and I’d have to run an air purifier. I’d often worry about the vapor leaving slight residue all over my apartment, belongings, monitors, PC internals and such.
Overall, it was great for a while as it was something I got really into, but it was also a lot of money and stress over something that didn’t really benefit my life the way other hobbies still continue to do. Much better to be a free person unattached from adult security blankets. 😎
I think you’re right to complain, but at the same time, aren’t single use plastics much lower on the pollution scale than, say, the fishing industry or other industrial plastic pollution? It makes sense to reduce and reuse, I try - but also find it beyond helpful to have a bunch of (unorganized) baggies strewn about for things like loose screws, storing filament spools, organizing USB cables, etc. I could definitely use something like this instead of a black hole under my sink. I know it’s easy to judge – esp without the whole picture – and hopefully people aren’t polluting willy nilly, but curiosity is a better approach than judgment or shaming when it comes to changing minds, wouldn’t you agree?
I really enjoy the podcast Deeper Dating. The host, Ken Page, is one of the most emotionally in-touch men I’ve heard from. More so than a lot of women, honestly. Also, therapy and men’s groups are a great start too. Consider poetry, talks from Brené Brown, books on attachment styles, and engaging with more emotionally intimate people in your life - even just as friends, male or female.
I was just thinking about this the other day. It’s weird how Google has become so unusable due to its own practices that it seems to be giving up on being a search engine. I’ve been getting spam pop-ups lately on mobile search asking me to use AI. Of course people will wanna use it, they can’t find their answers normally anymore. You search for something and it’ll show you something completely unrelated because it’s trying to be “helpful” and corral you towards buying shit, and it doesn’t even do a good job at that. Heaven forbid you start to look past the first 3 pages… I don’t have a clue how these websites in the search results are maintained when they’re filled solely with spam and nonsensical gibberish. I’m totally with you. We used to actually see communities around and now it seems like they’ve fallen into the dark web, unfindable except by means of knowing someone who knows someone or, frustratingly, reddit. Paradoxically, it’s like the random AI-generated hash from the dark web is now here clogging up the tubes. I feel like everyone else came along and started dumping trash everywhere because we didn’t put up any signs or make any rules not to litter.
This is just one perspective, but people-pleasing is when you go overboard with being considerate of others – to the point that you lose yourself. So like the one friend who will say they like all the same things as you, say yes to everything, never disagree, etc. just because they desperately need you to like them. They don’t have boundaries, so even when someone hurts them, they’re like “it’s okay, I don’t mind!” They’re missing a bit of self-respect.
There’s nothing wrong with being kind or considerate of others! It’s really important to have to form deeper relationships. The problem is when seeming ‘nice’ takes the place of your personality or being honest about your real self, because you value other’s validation more. People can sense that and it can put them off because they want to get to know the real person. People-pleasers can play the character that they think others want them to be, instead of putting in the work to like and value themselves and communicate their own needs and boundaries.
I feel like what would honestly be easiest would be to just have some tahini on hand as a backup. It is sesame so it’s not a true substitute, but also it lasts for ages so there isn’t a huge reason to not have some around.
You know, if you think about it, there are a ton of inventions that have been created as a means of that same process of experimentation with divergent thinking. Who knows what you could end up finding out :)
Look up instructions for your slicer on how to get the weight (in grams) of an object before it prints.
Take your spool, and weigh it – ideally with a kitchen scale, in grams.
Go to this website and find your empty spool weight.
Subtract the spool weight from the kitchen scale weight. This is how much filament you have left.
Compare the number from your slicer to the filament you have left.
If you’d like, you can also look into getting a filament runout sensor so you don’t have to hover over your printer to catch when exactly it runs out of filament. It’ll automatically stop the print so you can replace to spool.
